I had a similar issue with the load/unload on a Green drive, my take is that they are either not tested beyond the spec (unlikely) or that beyond the spec there are reliability issues. I know the WD are rated @ 300k cycles, hence I would think that at 170% of that it is flag I would pay attention to. But of course it could go for another 10 years or fail in 10 seconds! :-)
Just to note that replacement drives are "re-certified", not refurbished. One (not I) could argue that since they have undergone even more testing than a new drive they should be at least as reliable.... :-) Most likely they are just "no fault" returns, replaced mobo or firmware upgraded. The only "unknown" is how much action they have seen, since I guess they wipe the SMART stats. That's the only reason I won't put my data on them!
